Evaluation of the efficacy of pulsed radiofrequency therapy in patients with lumbosacral radicular pain: An analysis of single-center data.

OBJECTIVES: Lumbosacral radicular pain (LRP) is one of the most common causes of neuropathic pain. This pain often arises from inflammation in the dorsal root ganglia (DRG) or spinal nerves. Despite various treatment modalities, success rates are not very high in chronic LRP cases. Pulsed radiofrequency (PRF) therapy, frequently applied to the DRG, is widely used, but its effectiveness is often questioned in various studies. The primary aim of our study is to evaluate the effectiveness of PRF treatment in 154 patients. METHODS: Patients with LRP for longer than 3 months, treated with PRF, were included in this study. To assess the efficacy of PRF treatment, numerical rating scale (NRS) scores were evaluated at the 4th-week and 6th-month follow-ups. RESULTS: The NRS scores were significantly lower at the 4th-week and 6th-month follow-ups compared to pre-treatment levels (p<0.001). However, there was no significant difference between the mean NRS scores at the 4th week and 6th month. CONCLUSION: Success in interventional pain procedures is often considered as at least a 50% reduction in pain scores. The success rate for PRF treatment for LRP in the literature varies between 30% and 60%, which is similar to our findings at the 4th week and 6th month. PRF treatment is widely used due to its low side-effect profile and cost-effectiveness in the long term. There is no fully standardized practice regarding procedural aspects, such as the duration of the application, and prospective studies with larger participation are needed.

Comparison of the diagnoses, the outpatient clinics they visited, and the number of visits of patients with and without a diagnosis of fibromyalgia syndrome: Do patients with fibromyalgia syndrome come to the hospital more often?

OBJECTIVES: Fibromyalgia syndrome (FMS) has a wide spectrum of symptoms that includes all body parts. So FMS is a great imitator. This brings to mind the possibility that fibromyalgia patients visit outpatient clinics in many departments more than non-fibromyalgia patients. However, there is not enough data on this subject. This study aims to compare the number of outpatient visits of patients with FMS with those without a diagnosis of FMS and to examine their diagnoses. METHODS: The diagnoses of 140 patients (70 with fibromyalgia and 70 controls), and departments of the outpatient clinics they visited were analyzed retrospectively. In the control group, patients who visited the same outpatient clinic with the complaint of knee pain, but who did not have FMS and who had never been diagnosed with FMS before, were recruited as age- and gender-matched. RESULTS: The total number of outpatient clinic visits, as well as the number of visits to physical medicine and rehabilitation, obstetrics and gynecology, general surgery, internal medicine, and psychiatry departments, were significantly higher in fibromyalgia group patients compared to the control group. In addition, the number of diagnoses in the 5th chapter (mental, behavioral, and neurodevelopmental disorders, F01-F99) of International Classification of Diseases-10 was significantly higher in the fibromyalgia group. CONCLUSION: It should be kept in mind that patients with FMS visit more hospitals and outpatient clinics than other patients. Physicians and patients should be informed about this issue to reduce unnecessary health costs.

Do the presence, size, and shape of plantar calcaneal spurs have any significance in terms of pain and treatment outcomes in patients with plantar fasciitis?

BACKGROUND: : The purpose of this study was to determine the effect of the presence, size, or type of calcaneal spurs on pain or the outcomes of extracorporeal shock wave therapy (ESWT) therapy in patients with plantar fasciitis. METHODS: Seventy-four patients with unilateral plantar fasciitis who had no pain in the contralateral foot, either currently or in the past, were included in the study. The length, base width, type, and presence of plantar calcaneal spurs in both heels of the patients were determined using radiography. A total of five sessions of ESWT (3 bar, 2000 shocks/session, 12 Hz frequency) with an interval of 3 days were performed on the painful sides of the patients. Symptom duration and numerical rating scale (NRS) scores were recorded pretreatment and 1 week and 12 weeks after treatment. RESULTS: : Spurs were detected in 85.1% of painful feet and 71.6% of painless feet, this difference was statistically significant (p = 0.046). There was no significant correlation between the type of the spurs and whether the foot was painful. Patients with spur sizes of >5 mm or with horizontal and hooked spurs had a higher NRS decrease than patients with spur sizes of ≤5 mm or with a vertical spur. Symptom duration, spur length, and base width were found to be correlated with pretreatment NRS scores. DISCUSSION: The presence and size of calcaneal spurs are associated with pain. However, it should be kept in mind that a high rate of spurs can also be found in painless feet, so spur is not the only factor that causes pain. Patients with a spur size of ≤5 mm or a vertical spur have less pain relief with ESWT.

Does osteoporosis cause pain even without a fracture? An observational study.

INTRODUCTION/BACKGROUND: Osteoporotic fractures are usually painful. However, data on whether osteoporosis without fracture causes pain are insufficient. This study aims to determine whether osteoporosis without fracture is the cause of pain. METHODOLOGY: Patients aged over 18 years who visited the Physical Medicine and Rehabilitation outpatient clinic of a tertiary university hospital for dual-energy X-ray absorptiometry scan and were suitable for dual-energy X-ray absorptiometry scan without a history of fracture were included in the study. Patients with a history of fractures or those with fracture/fracture sequelae on X-rays were excluded. The cervical, lumbar, and thoracic spine and general body pains of the patients were questioned and dual-energy X-ray absorptiometry results were recorded. RESULTS: The study was conducted with 139 patients. Lumbar bone mineral density and T score values of the patients were found to be negatively correlated with the numerical rating scale levels of the cervical, thoracic, lumbar spine, and general body pain. Hip total bone mineral density and T score values were also negatively correlated with numerical rating scale scores of the lumbar and thoracic spine and general body pain. When the patients were divided into two groups as those with and without osteoporosis, it was found that the cervical, lumbar, thoracic spine, and general body pain numerical rating scale levels of the patients with osteoporosis were significantly higher than the group without osteoporosis. CONCLUSION: The results of this study showed that osteoporosis might be associated with pain even though there is no fracture.

Effect of neuropathic pain on sphenopalatine ganglion block responses in persistent idiopathic facial pain.

OBJECTIVES: Management of persistent idiopathic facial pain (PIFP) can be challenging. Sphenopalatine ganglion (SPG) has been the target for the interventional treatment of many facial pain syndromes. However, possible factors that may affect SPG block success are unknown. It was aimed to investigate the effect of neuropathic pain on SPG block outcomes in PIFP, which includes a heterogeneous patient group. METHODS: All of the patients underwent fluoroscopy-guided SPG block with an injection of 40 mg of 2% lidocaine and 8 mg of dexamethasone. The patients were assigned to 2 groups according to existence of neuropathic pain determined with the DN4 questionnaire score: 19 patients with neuropathic pain (Group 1) and 15 patients without neuropathic pain (Group 2). Preprocedural and postprocedural Visual Analog Scale (VAS) scores were compared between the 2 groups. RESULTS: The mean age of the patients was 47.65 ± 6.50 years. The average pain duration was 52.95 ± 34.81 weeks. A significantly greater decrease was detected in the VAS scores at 1 week (p = 0.036) and 1 month (p < 0.001) in Group 1 when compared to Group 2. Moreover, the proportion of patients with >50% improvement in the VAS scores at 1 week (p = 0.012) and 1 month (P = 0.017) was significantly lower in Group 1 than in Group 2. DISCUSSION: SPG block appears as a safe, effective, and rapid method to treat PIFP, especially in cases with neuropathic pain. Neuropathic pain may be a predictor for pain relief in interventional procedures targeting SPG in the treatment of PIFP.

Effects of splinting and three injection therapies (corticosteroid, autologous blood and prolotherapy) on pain, grip strength, and functionality in patients with lateral epicondylitis.

Objectives: This study aims to compare the efficacy of the wrist splint and the injection of corticosteroid, autologous blood, and hypertonic dextrose in the treatment of lateral epicondylitis (LE). Patients and methods: A total of 120 patients (43 males, 77 females; mean age: 45.7±7.7 years; range, 18 to 65 years) diagnosed with LE between December 2013 and June 2015 were included in the study and randomized into four groups. The first group was administered 20 mg methylprednisolone acetate + 2 mL 2% prilocaine, the second group 2 mL venous blood + 0.5 mL prilocaine, and the third group 2 mL 30% dextrose + 0.5 mL prilocaine injections. A second injection was administered to the third group one month later. The fourth group was recommended to use only a wrist splint. Pre-treatment and post-treatment evaluations of the patients were carried out at one and six months by the Visual Analog Scale (VAS) in terms of pain, by Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire in terms of functional level, and by the Jamar dynamometer in terms of grip strength. Results: In all groups, VAS values at one and six months after treatment were found to be lower in comparison to baseline. Except for the splint group, a significant improvement was observed in all three injection groups in terms of grip strength and PRTEE values at six months compared to the baseline values. In the comparison of the groups, no significant difference was observed in terms of improvement in VAS scores and grip strength. While corticosteroid injection was significantly effective in terms of PRTEE pain, function, and total scores only at one month, the autologous injection was effective in terms of PRTEE function and total scores at only six months after treatment. There were no significant differences for splint and prolotherapy groups in terms of PRTEE scores. Conclusion: Corticosteroid injection, autologous blood injection, and prolotherapy are effective and safe long-term methods in LE treatment.
